network buffer size?
Should be...
# sysctl net.core.rmem_max
net.core.rmem_max = 50000000

Hello,
We lately bought 2 new NUC devices (a NUC7i7BNH and a NUC6i7KYK),
installed Debian 9 on it and tested Gnuradio on it. At first we
installed via apt-get. We saw some drops in the gnuradio-companion and
had issue with setting the real-time priority, so we removed it from
the system and installed it again with pybombs.
However, no difference. Today tested it again with UHD provided
benchmark example (for easy reference). Saw occasional drops with Sps
from 1e6 to 10e6. Thought it might be a network driver issue, updated
the Intel network driver with the latest(?) e1000e driver. Still no
difference.
Any ideas, can we fix this somehow?
Thank you
Meelis
